Sherlock was pacing, glancing at his phone every 30 seconds. No, no, no! This was not allowed to happen. Moriarty wouldn't harm his son. He tried to swallow his anger. It spilled into the knuckles and his fist connected with the wall. The pain didn't register as he struck the same spot again and again, then hearing a loud crack he winced and cradled his hand with the other.
His phone chose that moment to ping.
Sherlock don't go breaking your body. That's my job. –JM
Texting with one hand proved to be a challenge while the other was throbbing so much.
Tell me what to do…You've won. I don't want to play games. Just leave my son and John alone.-SH
Sherlock's phone buzzed in his hand. He answered
"Moriarty , please just listen to-"
"Daddy?" Hamish's terrified voice squeaked through the phone.
Sherlock emitted sounds that weren't human, as you could hear his heart break and it echoed in his voice.
"Hey 'Mish, (he swallowed the lump in his throat) Daddy is going to come and get you okay? Where are you? The flat? Where is Dad?" He controlled his voice well, not letting it crack this time.
"Yes, we are still at home…Dad Help!-" A muffled noise on the other end then Jim's high pitched voice spoke clear.
"Ready to play yet Sherlock? Hamish really is a lot of fun but not quite up to my standards yet. He doesn't know how to squirm right." Jim said.
"Jim…tell me what to do ...whatever you want I'll do it!"
"Come on home love. John needs your assistance!" his voice soared at the end and the line went dead.
The next few minutes where in slow motion. Sherlock tearing out of the lab, shoes hitting the ground his long coat fluttering behind him. He didn't even hail a cab! He just kept running. He was earning the odd looks of the people he passed by but he didn't care all he could think about was the man he loved and his child in the grasp of Moriarty.
He was turning onto his block ,his feet willing him to go faster .
Almost there… Sherlock could see the door. 5 steps…
4 steps…3…2…1…
